Abstract

The embodiment of the invention discloses a file transmission method and device, a server, equipment and a medium. The method comprises the following steps: acquiring a file uploading online request of the intelligent equipment; wherein the file uploading online request carries a code ID of the intelligent device, abstract information of an original file and first abstract information of an encrypted file; generating an uploading mark character according to the code ID of the intelligent device, and returning the uploading mark character to the intelligent device; receiving a file content uploading request sent by the intelligent device; wherein the file content uploading request carries an uploading mark character and encrypted file content; verifying the uploaded mark character; verifying the encrypted file content and the decrypted file content of the encrypted file content; storing decrypted file content. According to the embodiment of the invention, the content of the encrypted file and the content of the decrypted file can be verified, the problem that the content of the file is tampered in the transmission process is solved, and the reliability and integrity of file contenttransmission are effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of file security, and in particular, to a file transmission method, device, server, device, and medium. Background technique [0002] The IoT device management platform manages a large number of IoT devices and various smart terminals in the bank. With the development of business, there is a need to upload and download files in many business scenarios; for example, if some abnormality occurs in the device, the log file of the device needs to be collected For analysis; the face recognition function of the device needs to transmit the collected face information to the face recognition system through the IoT device management platform for face recognition. Therefore, the utilization rate of file upload and download functions has increased significantly. At present, the file upload and download functions implemented in the industry are to directly upload the source files when uploading and downl...
